Using VNC Client to Manage Remote Server

You can use a standard open VNC client to manage the remote server using both desktop and mobile devices such as

Dell Wyse PocketCloud. When servers in data centers stop functioning, the iDRAC or the operating system sends an

alert to the console on the management station. The console sends an email or SMS to a mobile device with required

information and launches VNC viewer application on the management station. This VNC viewer can connect to OS/

Hypervisor on the server and provide access to keyboard, video and mouse of the host server to perform the necessary

remediation. Before launching the VNC client, you must enable the VNC server and configure the VNC server settings in

iDRAC such as password, VNC port number, SSL encryption, and the time out value. You can configure these settings

using iDRAC7 Web interface or RACADM.

NOTE: VNC feature is licensed and is available in the iDRAC7 Enterprise license.

You can choose from many VNC applications or Desktop clients such as the ones from RealVNC or Dell Wyse

PocketCloud.

Only one VNC client session can be active at a time.

If a VNC session is active, you can only launch the Virtual Media not the Virtual Console.

If video encryption is disabled, the VNC client starts RFB handshake directly, and a SSL handshake is not required.

During VNC client handshake (RFB or SSL), if another VNC session is active or if a Virtual Console session is open, the

new VNC client session is rejected. After completion of the initial handshake, VNC server disables Virtual Console and

allows only Virtual Media. After termination of the VNC session, VNC server restores the original state of Virtual Console

(enabled or disabled).

To configure the VNC server settings:

In the iDRAC7 Web interface, go to Overview → iDRAC Settings → Network → Services.

The Services page is displayed.

In the VNC Server section, enable the VNC server, specify the password, port number, and enable or disable SSL

encryption.

For information about the fields, see the

Click Apply.

The VNC server is configured.

To configure the VNC server, use the VNCserver object with the set command. For more information, see the

RACADM Command Line Reference Guide for iDRAC and CMC available at dell.com/support/manuals.

While configuring the VNC server settings in iDRAC, if the SSL Encryption option was enabled, then the SSL tunnel

application must be used along with the VNC Viewer to establish the SSL encrypted connection with iDRAC VNC server.

NOTE: Most of the VNC clients do not have built-in SSL encryption support.
